摘要

银码是一种实现认知无线网络中多天线系统分集-复用增益最佳权衡的2x2空时分组码。本文首先分析了Silver码的译码方法，然后分析了Alamouti码和V-BLAST码在瑞利衰落环境下的性能。仿真结果表明，在高信噪比下，银码的性能优于Alamouti码和V-BLAST码。

Bit error rate analysis of cognitive radio under fading channels

The Silver code has been proposed as a 2 × 2 space time block code that accomplish the optimal diversity - multiplexing gain tradeoff for a multiple antenna system in Cognitive Radio Network. In this paper the decoding methodology for the Silver code is analyzed, followed by performance analyzing with the Alamouti code and V-BLAST in Rayleigh fading environments. Simulation results show that the Silver Code outrun both the Alamouti code and V-BLAST at high SNR levels.
